I purchased this book to help me with all my assignments at University and have found it to be remarkably useful. Just today, (ironically) I found a section in the back that deals with cases insofar as their year, litigants, verdict, and over all results go. I have even gotten away with not purchasing books for two classes this semester and, instead, relying on this book. Today is my last day of finals and my GPA is a 3.6, so the gamble paid off.
On the short side, it's amazing what this book will not have within it. Some of the more complex but commonly used terms wont be included in this book. The only reason I can fathom is because this book was written mainly for professionals and not students, so the terms not listed would be more common knowledge to them and not necessary to include in the book.
